Did some searching around on the net once in regards to the Barlow Knife. It seems that George Washington commisioned a local knifemaker in Valley Forge? by the name of Barlow to come up with a serviceable knife for his troops. Thus the Barlow Knife was born. Its a knife which has two blades which flip out at the same end. Usually the handle was finished in some kind of bone or staghorn. Not being an expert on American folk history I can only accept what I found to be a reasonable tale. Stew
